Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE3303F100QG are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating voltage compatibility (12VDC or higher rated)
• Mounting type (Surface Mount)
• Actuator orientation (Top Actuated)
• Termination style (Gull Wing)
• Outline footprint compatibility (6.20mm x 6.00mm or equivalent)
• Switch travel distance (0.25mm)

Allowable Parameter Variations:

• Contact current rating may exceed 0.05A (higher rating acceptable)
• Operating force may vary (100gf to 160gf acceptable for same actuator type)
• Actuator height may vary within ±0.60mm (2.50mm to 3.10mm acceptable)
• Operating temperature range may be wider (extended range acceptable)
• Mechanical life may exceed 100,000 cycles (higher cycle rating acceptable)
• Packaging format may differ (Tape & Reel or Bulk acceptable)

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active production status and meet RoHS compliance requirements, ensuring regulatory alignment with the original TLE3303F100QG specification.

FSM2JELGELTR provides the closest electrical and mechanical match to the TLE3303F100QG, with identical contact rating (0.05A @ 12VDC), operating force (100gf), and switch travel (0.25mm). This part features extended mechanical life (1,000,000 cycles versus 100,000 cycles) and a wider operating temperature range (-35°C ~ 85°C). The actuator height is reduced to 2.50mm, and the outline is 6.20mm x 6.20mm. This part is suitable for applications requiring identical electrical performance with enhanced durability.

1977263-1 and FSM1LPSTR are functionally compatible substitutes rated for higher voltage operation (0.05A @ 24VDC), making them suitable for applications where the circuit voltage may exceed 12VDC. Both parts feature increased operating force (160gf) and extended mechanical life (1,000,000 cycles). FSM1LPSTR is available in Tape & Reel packaging, while 1977263-1 is supplied in Bulk format. Both support wider operating temperature ranges (-40°C ~ 105°C).

Frequently Asked Questions (FAQ)

Q: Can FSM1LPSTR be used as a direct replacement for TLE3303F100QG in a 12VDC circuit?

A: Yes. FSM1LPSTR is rated for 0.05A @ 24VDC, which exceeds the 12VDC requirement of the original part. The higher voltage rating provides margin for circuit operation. All other critical parameters—circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Surface Mount), actuator orientation (Top Actuated), termination style (Gull Wing), outline dimensions (6.20mm x 6.00mm), and switch travel (0.25mm)—are identical or compatible.

Q: What is the difference between FSM2JELGELTR and FSM1LPSTR?

A: FSM2JELGELTR is optimized for 12VDC applications with 100gf operating force and 2.50mm actuator height. FSM1LPSTR is rated for 24VDC operation with 160gf operating force and 3.10mm actuator height. FSM2JELGELTR offers closer mechanical similarity to the original part, while FSM1LPSTR provides higher voltage capability and increased operating force. Both deliver 1,000,000 cycle mechanical life.

Q: Does the 0.60mm difference in actuator height between TLE3303F100QG (3.10mm) and FSM2JELGELTR (2.50mm) affect PCB layout compatibility?

A: The reduced actuator height of FSM2JELGELTR may affect tactile feedback characteristics and clearance to overlying components. PCB layout review is necessary to confirm adequate clearance above the actuator. The gull wing termination and outline footprint remain compatible.

Q: Are all substitute parts available in the same packaging format as the original TLE3303F100QG?

A: The original TLE3303F100QG is supplied in Tape & Reel (TR) packaging. FSM1LPSTR is also available in Tape & Reel format. FSM2JELGELTR is available in Tape & Reel format. 1977263-1 is supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain RoHS compliance status. FSM2JELGELTR carries RoHS compliance certification. 1977263-1 and FSM1LPSTR carry ROHS3 compliance certification, matching the original part specification. All parts are REACH Unaffected and carry EAR99 ECCN classification.
